I believe the answer is:

daliesque

I'm a little stuck... Click here to teach me more about this clue!

'hostage' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'spread a lie squeamishly surreal' is the wordplay.
'DALIESQUE' is hidden within the letters.
However, I am not sure how this is indicated.

'to' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
